title: High-performance oxygen reduction electrocatalysts based on cheap carbon black, nitrogen, and trace iron.
abstract: A real optimal Fe content: For N and Fe co-doped carbon electrocatalysts for oxygen reduction reactions (ORRs) it is found that there is a real optimal trace Fe content (Peak II), which has never been observed before. The real optimal electrocatalyst shows superior high activity for ORR and possesses the best price/performance ratio ever.
